Investigated the laboratory behavior strategies of 600 class five biology students (319 boys and 281 girls) associated with attitudes toward laboratory work and improved performance in such practical skills as planning and design of experiments and the observation, recording, and interpretation of data.

Investigated what physics students (N=38) recalled from reading text material related to energy transfer. Four different groups of students, each recalling different sets of propositions, were identified suggesting that science educators cannot assume that all students in a class will recall identical information from the assignment of a reading…

Compared levels of formal operational thought of students tested before and after entering science programs. Results indicate considerable numbers of students at transitional levels on each occasion, low correlations between cognitive level and grades, and significant development in levels of cognitive thought during the National High School…

Discusses a study designed to understand 11th-grade students' learning during conversations with their teacher over and about a computer-based Newtonian microworld, Interactive Physics. Illustrates that students' learning was not local but persistent, in that they used appropriate canonical science talk without teacher support. (36 references)…

Determined differences between lecture-demonstration and small-group laboratory approaches on students' (N=74) chemistry achievement and attitudes toward science. Findings indicate that students taught by the laboratory approach achieved better on immediate/delayed posttests than students taught by lecture-demonstration method. More desirable…

Employed an interpretive methodology to examine interrelations between teacher and student actions in a context of teaching and learning in a grade-11 chemistry class. Teacher and student goals, beliefs about teacher and learner roles, and constructions of the context were coherent to such an extent that there was little impetus for change. (24…
